LT3507AEUHF Description

Short technical summary and product information.

The LT3507AEUHF by Analog Devices is a versatile triple monolithic step-down DC/DC converter with an integrated low dropout linear regulator. It is designed for a wide input voltage range of 4V to 36V, making it suitable for various power supply applications.

 

The device features one switching regulator capable of delivering 2.7A and two others capable of 1.8A each. All three converters are synchronized to a single oscillator, and the 2.7A output operates in antiphase to the other two, which helps reduce input ripple current. The switching frequency is adjustable from 250kHz to 2.5MHz via a single resistor, allowing for the use of small inductors and ceramic capacitors, thus enabling compact triple output power supplies.

 

Each regulator has independent shutdown and soft-start circuits, along with a power good signal, which simplifies power supply sequencing and interfacing with microcontrollers and DSPs. The LT3507AEUHF is available in thermally enhanced TSSOP-38 and QFN-38 packages, suitable for surface mount applications.

 

This regulator is designed for applications such as automotive and industrial supplies, and distributed power regulation, offering flexibility and efficiency in power management.
